[FONT=Verdana,Arial,Times New I2]I've noticed my microworms don't climb very much. At any given time, only one of the seven cultures I currently have growing will have significant numbers of worms on the walls. I've tried adding more water and letting them dry out more but neither of these induced climbing. But, when I seal the cultures so that fresh air can't get to them, the worms start climbing within minutes. If the cultures are then uncovered, they pull back into the growing medium. This indicates that restricting air is an effective technique to get microworms to climb.[/FONT]
